Even if the Belfast was not built, Shorts could manufacture parts for other aircrafts (as they did with the Fokker 100, perhaps with other Fokker as well). They had also their own designs, suc has the Skyvan and the 330.
I thought the Andover for transport everything it can hold internal in United Kingdom and the 681 for strategic lift. The C-130 is one of the best transport planes ever built, but AS designed from Lockheed. Personally I doudt if the Tyne-C130 was better, judging from the Spey-Phantom. The fighters is another large chapter to discuss.
My VC10 AEW is based on the Standard airframe and has the equipment from the E-3 Sentry. The Nimrod AEW swallowed 1m English pounds and was a dead end, this I suggest previously would be more cost effective.I also agree to that you wrote about RAF VC.10, perhaps some more converted later.
The DH Trident with Medways was the Avro 776?
That Hood wrote about Handley Page reminds me histories I read about the closure of some OKBs in Soviet Union during Stalin era.
However, the Herald is equivalent with the Fokker F27 in range, the Andover has much short legs but a rear door similar with C-130, so it could be loaded more easily. Perhaps a Herald with rear door similar with Andover is perhaps a good solution.
Supposed the HP.111 was ordered and built, would it be efficient?
Americans in NATO want the market for themshelves only, but this would led to an agreement to let United Kingdom sell in Commowealth countries and to any other country want English weapons. In other words, US let UK to compete in national contests for military equipment. But this is political question, here we examine aircrafts mostly from technical side.
P.S Some days ago I searched for information about the Avro Atlantic, some guys built an what if military Atlantic,
http://www.britmodeller.com/forums/inde ... tic-cmk-2/, is there any role this aircraft would fulfill or just leave it? As a passenger aircraft had the same problem with Comet, inside noise due to engines position.
